.provements in Portable Hand-Operated Suction-Cleaners, of which the following is a specification, reference being had therein to the'accompanying drawing.

- Mypresent invention relates to improvements in portable hand-operated: suction cleaners,'the main object being the provision of a cleaner, which is provided with-a sue tion head, having a detachable vibrating brush,a suction fan and means for operating the fan and brush, .said means being readily accessible to the operator as a handle is attached to the suction head, and the operating means is attached to said handle, whereby with one hand'the operator may pull or push the suction head over the sur face to be cleaned, while operating the fan and brush. with the other hand- To clearly illustrate my invention, attention'is invited to" the accompanying drawings, in which Figure 1 is a front elevation of the cleaner, the handle being shortened by breaking it away intermediate of its ends. Fig.v 2 is aside elevation thereof. Fig. 3 is. a section through the suction head on line w -a: Fig.2'looking in the. direction of the arrow, the suction head being made substantially fullxsized; Fig. 4 is a similar view taken on line y--y, Fig. 1, looking in the direction of the arrow. Fig. 5 is a section on line zz Fig; 2. Fig. -6 .is an enlarged section through the device forimparting a vibratin motion to the rod and its brush..- Fig. 7 1s a top plan view of the disk carried upon the upper end of the brushs rod, and Fig. 8 is a bottom plan view of the diskcarried by the lower end of the rotatable shaft.

Referring to the drawings :the numeral 1 designates the complete suction head or casing, having the enlarged fan. carrying portion 7 and the reduced suction end- 3, whose front wall 4, is removably held in place by means of the thumbscrew 5, which passes through the wall 4' and enters the threaded socket of one of the lugs 50. Mounted within the mouth of the suction head-are the two casters or wheels ,6, which permit the device to be easily pushed or I Specification of: Letters Patent.

I pulled over thesurfaceto be cleaned. The

fan carrying portion 7, is provided? with the removable dome 8, which is secured thereto by means of the bolts 0?, thus permitting ready access to the interior of the suction head from above. The casing is provided with an outlet spout 9,-which has removably attached thereto the air filtering and dust and dirt collecting fabric bag or receptacle A, whose other end is closed and 'detachably connected to the tubular handle 14', by means of the clip 11 and thehook 13'. By this means, when the bag or receptacle is filled with dust and dirt, the clip-L1 is removed from the hook 13 and; the clip re- .moved from the mouth 12, of the bag, thus permitting the mouth to open and allow the operator tocause the dust and dirt to fall out throu h said mouth 12.

In the ower-part of the enlarged portion 7, of the suction head or casing, I mount two brackets 15 and 15', each one of which is provided with alined openings for the rotatable reception of the shaft 18, which has keyed thereon the disk 17, carrying the fan blades 19, and to reduce the friction between the disk 17 and the bracket 15, 1 employ the ball thrust bearing 16, as clearly shown in Figs. 3 and 4. It will be seen that it is only necessary to rotate the shaft 18 to cause the fan blades 19- torotate and create a suction within the suction head so that air and dust and dirt are drawn into the-casing at its lower mouth 20, and forced out through the outlet 9, into the airfiltering and dust and dirt collecting bag A.

To rotate the fan, I mount upon theupper end of the shaft 18, the bevel gear 21, which evel gear 22, which is mounted upon the lower end of the flexible shaft 23, which shaft is preferably a wire formed shaft, such as is used in dental en ines. The lower end of the shaft 23 is lded in the small sleeve 23, carried in the dome of the fan chamber, while the remain- ;der of the said shaft 23, is incased in the hollow handle 14 and the hollow boss or through and supported in the sleeve' 23',

which is of such a length as to insure, when the shaft 23 is properly tightened, the proper meshing at all times of the gears 22 and 21. When properly assembled, the small gear 24 is meshing with the operating gear 25, while the gear 22 is meshing with the gear 21, thus insuring the rotation of the shaft 23 when the gear 25 is operated, this rotation of the shaft 23 insuring the rotation of the shaft 18 through the gears 21 and 22. p

. Detachably connected to the projection 60, so as to have a radial adjustment with relation to the suction head, by means of the split globular head 61, which encircles the projection 60, and is clamped at any desired angle by means of the clamping band 62, is the tubular handle 14, into which the shaft 23 passes and is journaled in the block 14.

Upon the upper end of the shaft 23, is

keyed the small gear 24, which mesheswith the teeth of the large gear 25, carried by the support 25, said gear 25 having a crank 26, by means of which the gear 25 is revolved, thus rotating the shaft 18 and fan blades 19, through the shaft 23 and its gearing. The toothed portion of the gear 25 :projects through the two slots 5 and I), cut

in the handle 14. By this. means, it will be seen that it is only necessary to push or ull the suction head or casing over the surface to be cleaned, simultaneously operating the gear 25 through its crank26.

a Secured upon the extreme lower end of the fan shaft 18, is a disk 45, which is pro- Vided with a series of three recesses 46, for the rotatable reception of the steel balls 47 which project through the apertures 48, of, the retaining disk 49, which is detachably secured to the disk 45, this memberforming the upper. and rotating member of my vibrator, and as shown in Fig. 8 is provided with three balls 47.

' Removably mounted in the space between the two lugs 50, of the suction head, is a 'rod 51, which is only adapted to have a vertical reciprocating movement, and upon the lower end of this rod is carried the brush D, whose extreme lower end when one of the balls 47 contacts one of the balls 55, will be projected below the extreme lower end of the suction head or be forced into contact with the surface to be cleaned to beat said surface and disturb or loosen the dust or dilte therein or thereon. The mechanism 'to project and return .the brush, consists of the disk 45 and its balls 47, and the disk 52 and its balls 55, said balls 55, being rotatably mounted in the recesses 53 of the disk I 52, and projecting exteriorly of the a ertures 54 of the retainingdisk 56, this isk and its parts being secured to the u per end of the vibratory rod 51. These balls 55 are upper side of the lugs 50. By

six vibrations are given to the brush, each rotation of the disk 45. In order to return the disk and rod 51, so that the balls may contact the spaces a upon the disks 49 and 56 between the balls, or cause the brush to assume the position shown in Figs. 3 and 4, I employ the coiled spring 57, which surrounds the rod 51 and abuts the underside of the disk 52, and exerts a tension against the disk 59, which in turn rests upon the this means the brush D, may be used as a disturber of the dust or dirt in the surface to be cleaned,

but should it not be used, the thumb-screw 5, is'released, permittin the wall 4, to-be removed, so that the ro 51 and its spring, brush and the lower member of the vibrator may be bodily removed, thus permitting the suction head to be used conveniently as a portiere cleaner.

To properly operate or manipulate my suction cleaner, the extreme upper end of the tubular handle 14, is provided with the D-shaped hand-grip 64, said hand-grip being placed at any desired angle that Wlll insure the easy manipulation of the cleaner.

What I claim, as new, is

1. In a device of this character, the combination of a casing having a suction end and a mechanism holding and fan chamber, a shaft journaled in the casing, a fan carried thereby, a rod slidably mounted in the casing below and inline with the shaft, a brush carried upon the lower end of said rod, a spring mounted upon the rod for holding the lower end of the brush within the mouth of the suction end,'co-acting means carriediby the lower end of the shaft and the upper end of the rod for causing the rotary motion of the shaft to intermittently project the rod against the tension of the spring, thereby giving-a reciprocating motion to the brush,

and mechanism for rotating said shaft.

2. In a device of this character, the combination of a casing having a suction mouth and a mechanism holding and fan chamber, a. shaft journaled in the casing, a fan carried thereby, a'rod capable of a longitudinally reciprocating movement mounted in the casing below theshaft, a brush carried upon the lower end of said rod, coacting means carried by the lower end of the shaft and the upper end of the rod for causing the rotary motion of the shaft to impart a reclprocating motion to the rod and brush, and mechanism for rotating said shaft. Y

3. In a device of this character, the combination of a casing having an elongated suction end and a mechanism holding and fan chamber, a shaft journaled in the casing, a fan carried thereby, a rod slidably mounted in the casing below and in line with the shaft, a brush carried upon the lower end I of said rod, a spring mounted upon the rod for holding the lower end of the brush Within the mouth of the suction end, a disk car.- 5 ried upon the lower end of the shaft, a disk upon the upper end of the rod, one of said disks being provided with an even number, and the other with an odd number of balls projecting into the same path, whereby as 10 the shaft rotates, the balls intermittently engage each other to re idly projectthe rod against the tension 0 the spring, thereby giving areciprocating motion to the brush, and mechanism for rotating said shaft.

In testimony whereof I aflix my signature 15 in presence of two witnesses.
